Abstract

Highlights: The battery charging and swapping station project has good environmental benefits, but poor economic benefits. This paper compares three different power purchase models. Direct power trading model can reduce the cost well and increase the NPV by 13, 519, 070.47 RMB. This model can be used in the economic evaluation of battery charging and swapping station projects and other charging facilities. Abstract: Battery charging and swapping station (BCSS) has great assistance for the development of Electric vehicles (EVs) and environmental protection, but its economic performance is poor. This paper aims to explore the feasibility of direct power trading in the charging and swapping market by comparing the economic benefits of BCSS under three different power purchase models. Firstly, this paper summarizes the differences between the three power purchase policies. Then, the environmental benefits of clean energy and coal power generation are compared. Finally, based on the cost-benefit theory, a pure electric bus BCSS in North China is taken as an example to analyze the benefits of the three power purchase models. The results show that compared with coal power generation, the use of clean energy has good environmental benefits. Compared with the other two models, the direct power trading model can significantly increase the project's NPV and IRR, which demonstrates that it can make up for the investment cost well. Some suggestions are put forward to improve the economic benefits of BCSS enterprises and promote the development of EVs. The research results can provide a reference for decision-makers and investors.
